Description
Technical field
The utility model is used for fish feed field, particularly relates to a kind of fish glue capsule feed.
Background technology
Microcapsules technology be world today's development rapidly, a kind of technology of of many uses and comparative maturity.The process preparing microcapsules is called microencapsulation, is by solid, and liquids and gases are rolled in a small capsule.Micro-encapsulated diet feed is encapsulated in completely by microcapsules technology the microcapsules formed in one deck dense film.Micro-encapsulated diet is for micro-sticky feed and mocromembrane feed, and the stability in water is better, and can reach bionical effect.
The application of micro-encapsulated diet in aquaculture is mainly reflected in: one, the fish meal of microencapsulation form, the feed ingredient such as amino acid and vitamin can not be made to be dissipated in because of water-soluble in briny environment destroyed; Two, micro-encapsulated diet by controlling particle diameter and the density of microcapsules, can make it be suspended in water and exactly liking planktonic organism, is conducive to juvenile fish predation; Three, after vitamin and feed addictive microencapsulation, the mutual work between them can be reduced, improve the palatability of feed, and the loss in process can be reduced, and can be controlled in the release of alimentary canal different parts.
Micro-encapsulated diet is mainly used in edible fishes and shrimps shellfish larval culture in aquaculture, and the cultivation for adult fish there is not yet report.Nylon protein film micro-encapsulated diet is used to replace biological feed to cultivate shellfish with Japan to the lower young if any researcher.Also there are some researches show, golden head porgy just can ingest when initial feeding the micro-encapsulated diet of protein film and carbohydrate film, and similar to live bait to the grazing rate of micro-encapsulated diet.Meanwhile, the micro-encapsulated diet of different wall material have also been obtained very large application in spotted maigre and pseudosciaena crocea larvae are cultivated.
But, although obtain certain progress with the research that micro-encapsulated diet replaces live bait to carry out aquatic product animal raise seedling, in the initial feeding phase, just can only rely on micro-encapsulated diet and make the kind of the fine survival of young acquisition also little.From the present situation of research at present, there are some problems in the application of micro-encapsulated diet in aquaculture.One, although some fish and shrimp young contain the digestive ferment of certain level, but still can not digest micro-encapsulated diet, may be because cyst material is the high molecular polymer of protein and Prof. Du Yucang, be difficult to be digested by the young, and the dry matter content contained by micro-encapsulated diet is far away higher than live bait; Two, micro-encapsulated diet can not obtain the feeding effect identical with live bait, may be not easily to be absorbed by the young due to the nutriment in capsule or can not meet needed for larval growth.
Therefore, to develop cheap further and easily by the microcapsule wall material that the young digests and assimilates, improve the production technology of microencapsulation further, the while of guaranteeing that nutriment is non-destructive, improving the digestive utilization ratio of micro-encapsulated diet.Micro-encapsulated diet can replace live bait wholly or in part, and has comprehensive nutrition, the feature cutting the waste and pollute, and all will play significant role to carnivorous aquaculture of aquatic animal and larval rearing.
In existing fish culture, for different fingerlings, the fish meal of production and supply on market, bait and bait form are different.Wherein there are nearly natural prodcuts, also the mixture of special synthesis is had, it keeps the natural form of feed mostly, does not do further specially treated, when fish are fed, directly feed is sprinkled into water body, eat for the fish in water body, due to the restriction of water body environment and the gloss of feed own, feed a part is difficult to is searched for food by fish and is deposited on the bottom, so not only cause a large amount of wastes of feed, and increase the weight of the desilting work in pond.

Be further used as the improvement of technical solutions of the utility model, the overall spherical in shape or elliposoidal of described capsule.
Be further used as the improvement of technical solutions of the utility model, the gelatin that described capsule and counterweight handle are formed in one, sodium alginate, zeins, ethyl cellulose, Arabic gum, shellac, lac or rosin product.
The beneficial effects of the utility model: fish all have phototaxis, one is that fish see light in water body, can feel " curiosity ", and produces the conditioned reflex of exploration and tend to light source; Two is for forage is ingested and tend to light source, as zooplankter in water body
copepods, small-sized shrimps, the infant animal such as small-sized crab class light source outside irradiation under there is very strong phototaxis, and be gathered in light source region, thus forage fish swum remove to look for food best bait to the migration region of zooplankter; Three is that the instinct of fish tends to its suitable illumination.
According to the above-mentioned characteristic of fish, this fish glue capsule feed wraps up one deck capsule shell in the outside of conventional feed, the outer surface of capsule is smooth bright, when being sprinkled into after in water body by this fish glue capsule feed, due to the light-reflecting property of bright of capsule self, it can attract the shoal of fish of surrounding, thus eaten by fish before feed does not fall into the bottom, thus avoid feed at subaqueous deposit, improve feed and to eat rate, avoid waste, alleviate the desilting work in pond; Because capsule has hydrolyzable or water-soluble characteristic, it on the one hand ensure that the security of ingesting that fish eat, also to make on the other hand in water body not by the capsule hydrolysis of eating or water-soluble after, the inner feed of release is for fish.
